The evidence provided is compelling, not just because the difference in outcome was profound, but because the intervention is benign. Asking patients to minimize screen time for 48 hours, provides caregivers with actionable practical advice that is unlikely to cause significant harm. It is important to note that given the subjective nature of concussion symptoms and the inability to blind subjects, screen time restrictions may have had a placebo effect which encouraged reduced symptom reporting. Further research is necessary to replicate these findings, better understand the ideal duration of screen-time restriction, and the biopsychosocial mechanisms underpinning its benefit. However, until that research is completed, restricting screen time during the first 48 hours of injury should become the standard advice in the acute phase of concussion recovery. The pandemic has shown us that for children, screen time is not always discretionary. This study provides the evidence-based guidance that caregivers need to advocate for their children during acute concussion recovery.
